A video distribution system includes a terminal device and a video data distribution device. The terminal device includes an identification information output part configured to output identification information representing first video data, which is generated from an original video, to the video data distribution device, and a video acquisition part configured to acquire second video data, which is generated from the original video and different from the first video data, from the video data distribution device. The video data distribution device includes an identification information acquisition part configured to acquire the identification information from the terminal device, and a video output part configured to output the second video data to the terminal device based on the identification information.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A terminal device comprising a processor configured to execute instructions stored in a memory in communication with a video data distribution device, wherein the processor is configured to: output identification information representing first video data, which is generated from an original video and obtained by the terminal device, to the video data distribution device; output setting information including presentation-start-point information representing a presentation-start point to start presenting second video data, which is generated from the original video after the presentation-start point, to the video data distribution device which is configured to store an identification information list representing the identification information in association with the first video data, the second video data, and the original video; and acquire the second video data from the video data distribution device, wherein the second video is generated from the original video captured by a plurality of cameras disposed at different positions according to the identification information.
2. The terminal device according to claim 1 , wherein the processor is further configured to: generate viewpoint information representing a viewpoint to capture the original video, wherein the viewpoint information indicates an imaging position and an imaging direction designated by the first video data such that the second video data is distributed from the video data distribution device according to the viewpoint information; and generate the setting information representing a setting of the second video data based on the viewpoint information.
3. The terminal device according to claim 1 , wherein the second video data is a three-dimensional video which is generated from the original video serving as a multiple-point video.
4. The terminal device according to claim 2 , wherein the viewpoint information includes a viewpoint position to capture the original video.
5. The terminal device according to claim 2 , wherein the viewpoint information includes a viewpoint angle to capture the original video.
6. The terminal device according to claim 1 , wherein the first video data has a smaller amount of data than the second video data.
7. The terminal device according to claim 2 , wherein the viewpoint information specifies a single camera among the plurality of cameras configured to capture the original video.
8. The terminal device according to claim 1 , wherein the second video data represents a specific model selected from among a plurality of models determined in advance.
9. A video data distribution device comprising a processor configured to execute instructions stored in a memory in communication with a terminal device, wherein the processor is configured to: acquire identification information representing first video data, which is generated from an original video, from the terminal device; acquire setting information including presentation-start-point information representing a presentation-start point to start presenting second video data, which is generated from the original video after the presentation-start point, from the terminal device; and output to the terminal device the second video data, which is generated from the original video captured by a plurality of cameras disposed at different positions with reference to an identification information list representing the identification information in association with the first video data, the second video data, and the original video.
10. The video data distribution device according to claim 9 , wherein the setting information represents a setting of the second video data according to viewpoint information indicating an imaging position and an imaging direction designated by the terminal device, thus distributing the second video data to the terminal device according to the viewpoint information.
11. The video data distribution device according to claim 9 , wherein the second video data is a three-dimensional video which is generated from the original video serving as a multiple-viewpoint video.
12. The video data distribution device according to claim 10 , wherein the viewpoint information includes a viewpoint position to capture the original video.
13. The video data distribution device according to claim 10 , wherein the viewpoint information includes a viewpoint angle to capture the original video.
14. The video data distribution device according to claim 9 , wherein the first video data has a smaller amount of data than the second video data.
15. The video data distribution device according to claim 10 , wherein the viewpoint information specifies a single camera among the plurality of cameras configured to capture the original video.
16. The video data distribution device according to claim 9 , wherein the second video data represents a specific model selected from among a plurality of models determined in advance.
17. An information distribution device comprising a processor configured to execute instructions stored in a memory in communication with a terminal device, wherein the processor is configured to: acquire video data; generate motion information representing a motion of a model representing a target image extracted from the video data, wherein the motion information is stored on a storage unit in association with target image information representing the target image; acquire terminal information of the terminal device representing a constraint regarding granularity of images displayable with the terminal device based on either performance information or communication quality information; adjust an information volume of the motion information to satisfy the constraint according to the terminal information so as to generate information-volume-adjusted motion information; and distribute the information-volume-adjusted motion information to the terminal device.
18. The information distribution device according to claim 17 , wherein the processor is further configured to acquire adjustment degree information representing a degree of adjusting the information volume requested by the terminal device according to the terminal information, and further adjust the information volume of the motion information based on the adjustment degree information.
19. The information distribution device according to claim 18 , wherein the model is selected from among a point model having a single element, a single-joint model having a plurality of elements, and a multiple-joint model having a plurality of elements and a plurality of joints, and wherein the processor is configured to adjust the information volume of the motion information by representing the multiple-joint model upon adjusting the number of elements included in the multiple joint model.
20. The information distribution device according to claim 9 , wherein the processor is further configured to acquire target image information representing a target image extracted from the video data, wherein the distribution part distributes the target image information to the terminal device together with the information-volume-adjusted motion information of the target image.
21. The terminal device according to claim 1 , wherein the setting information further includes a predetermined part of the second video data in the original video, communication quality information, and terminal information.
22. The video data distribution device according to claim 9 , wherein the setting information further includes a predetermined part of the second video data in the original video, communication quality information, and terminal information.
23. The terminal device according to claim 1 , which is configured to request the video data distribution device to distribute the second video data corresponding to the setting information upon a user's authorization.
24. The video data distribution device according to claim 9 , which is configured to distribute to the terminal device the second video data corresponding to the setting information upon a user's authorization.
